I bought a Delonghi ECAM 22.110.SB before the Spring Festival. In the past two weeks, there have been two lights flashing and the middle light is always on. The manual indicates: "the extraction time is too long or can not be extracted."

Keep pouring out my coffee powder, wow... The customer service staff of the company came to have a look, but they didn't try many cups that day, and they started again after two days. Today, even the automatic cleaning at the start-up time did not come out. The company said that it was necessary to move back to check in this way. I would like to ask if anyone else has encountered this situation?

Before doing homework to see a lot of people use ESAM3200 evaluation and durability are good, the most important thing is to know the evaluation of ECAM 22.110.SB.

Today again reported for repair, this situation is a bit strange, after washing and brewing a few cups, there is a problem again, sometimes after 3 or 4 cups, sometimes more than 10 cups are no problem, over and over again, pull independent power supply + use reverse osmosis water. Look at the repair and report it back to you!

The company moved back, but did not find an obvious problem. Later, he told me that the maintenance staff had adjusted to help Pu try it out. At present, there was no problem in use, but I felt that the sound of the pump for brewing coffee had become louder. I don't know if it's psychological.

The PUMP sound is relatively loud, you can try to see the action of removing calcium.

It is possible that the crystallization in the effluent area leads to the increase of effluent resistance.

This will cause PUMP to bear too much unnecessary pressure.

But it may not have an impact on the ontology.

In short, if you want to get rid of the problem that PUMP is too loud, consider the option of removing calcium.

I think there should be some defects when they leave the factory. I am most afraid of such a situation when shopping. Any brand may encounter anything. The most unfortunate situation is usually not long after the warranty. Embarrassed

I only used this machine for more than a month when something went wrong, and the water source is reverse osmosis water, so the part of calcium removal by crystallization should not be good, and the company didn't talk about this problem when I went back to dismantle the machine, so I can only continue to use it.
